Tutorial: Step by step

Step 1 Heat application

First, we apply heat to the back to soften the adhesive and to be able to peel it off.

Step 2 Back case

We introduce a metal tool to make our way and then we introduce a plastic spike-type tool so as not to damage the casing and we separate it around its entire contour until it is completely detached.

Step 3 Intermediate housing

With a Phillips screwdriver (PH # 00) we extract the eleven screws indicated to separate the housing from the terminal with a thin plastic tool.

With a fine opening tool we disconnect the battery to work more safely.
